Serving Suggestions

Here are my favorite ways to serve this potato dish:

This casserole is great on it’s own, but also pairs well with a variety of toppings. Think diced ham, colby jack cheese, extra shredded cheddar cheese, diced onions, or green onions.
Main dishes that go great with this are pork chops and onions, BBQ Crockpot back ribs, and Crockpot Ham, we also love to make air fryer fried chicken!
You can also serve it as a side dish with scrambled eggs, sausage, and bacon for breakfast.
The leftovers also make a great meal and can be turned into something new with a few extra sides and toppings (think baked potato toppings).

Recipe FAQs and Variations

How do I store leftover crockpot hashbrown casserole?

Place any remaining hash brown casserole in an airtight container and keep in the fridge for up to 4 days. Reheat in the microwave or oven until warmed throughout.

Can I use Greek yogurt instead of sour cream?

Greek yogurt tends to turn into water when put into hot dishes. I suggest using sour cream as the recipe calls for.

Can you cook this on low?

Yes, but I would not cook it longer than 4-5 hours on LOW.

Is the nonstick cooking spray necessary?

Yes, and you’ll want to be generous with it. You may also try a slow cooker liner to prevent sticking.

Any other variation ideas?

You can add cream of chicken soup, mushroom soup, use frozen diced potatoes, or add extra cheese to make cheesy potatoes.

Are you tempted to use Greek yogurt instead of sour cream? Don’t, for greek yogurt tends to turn watery when added to hot dishes.
